- RADIATOR AND COlL.

Specification of Letters Patent.

Patented Dec. 12, 1905.

Application filed March 19, 1904. semi No. 199,047.

To all whom, it may concern:

Be it known that I, JOHN H. LINDSAY, acitizen'of the United States, residing in the borough of Brooklyn, city of New York, county of Kings, State of New York, have invented a certain new and useful Improvement in Radi- 'ators and Coils, ofwhich the following is a specification.

The present invention relates to improvements in radiators or coils and means for attaching shields thereto, and has for its object to simplify the construction of the attaching means for the shield and reduce the cost thereof. 7

The invention also has for its object to improve the effect of the shield by using a plurality of shields instead of a single one.

Iaccomplish these objects by the device illustrated in the accompanying drawings, in which Figure l is a top View of the radiator, showing a shield partly in position. Fig. 2 is a front view; Fig. 3, an end view of the same; Fig. 4, an enlarged View in section through a portion of a radiator-section, showing in detail the manner of attaching a single shield. Fig. 5 is a similar view showing two shields in place.

In all of the several views like parts are designated by the same reference-numerals.

In carrying out my invention I provide certain of the radiator-sections 1 with integral lugs 2. These lugs are preferably formed near the top and bottom of a section and on both of the outside faces thereof, as is shown in Fig. 3. For simplicity I prefer to form the lugs on those sections which carry the feet 3, as thereby about the proper proportion of lugs to each radiator will be formed; but this is not essential. The shield 4 may be formed of sheet metal, preferably of a single piece of galvanized iron, and is secured to the radiator by means of the lugs 2. Separating the lugs and the shield and resting on the outer face of each lug is an extension-collar 5, preferably formed of cast-iron. The extension-collar has a hollow center, through which passes a bolt 6, the bolt also passing through a hole 7 in the shield and a threaded opening or tap 8 in the lug. The bolt is preferably a machine-bolt, and its head rests upon a washer 9, if such washer is desired. As many bolts as there are lugs are preferably used, in Fig. 2 there being six'such bolts illustrated on one side of the radiator, this being suflicient for a radiator composed of fifteen sections. For a radiator composed of a greater or lesser number of sections more bolts or less bolts will be used, as necessary.

In Fig. 5 I show two shields upon the same side of the radiator. The inner shield 10 is secured by the same securing-bolt as the outer shield 4'; but in lieu of a single collar 5 two collars 11 and 12 are employed. By this construction as many shields as desired may be used, the number of collars being increased and the length of the bolts being governed accordingly.

The openings 7 in the shield are preferably made with a' punch, which is a ready means of forming the openings in fitting the shield to the radiator. When so punched, each hole will havea bur 13 on the inner surface. Unless means be provided to accommodate this bur it will prevent the desired connection between the shield and the extension-collar. To permit such a close connection, the collar is counterbored at 14, the counterbore being sufficiently large to take all of the bur.

It is to be understood that the shield may be attached to either or both sides of the radiator,'as desired. 1

The broad invention disclosed herein is not claimed in this application, but in an application for Letters Patent filed by me on the 20th day of November, 1905, Serial No. 288,160.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In combination with a radiator having threaded lugs cast on the outside thereof, of a sheet-metal shield having punched perforations therein, counterbored spacing-collars between the shield and lugs, and screws for rigidly securing the shield to the lugs, the

said screws passing through the collars, and the saidi -scr'ews passing through the collars, :o the bur punched on the shield occupying the and the bur punched on a shield occupying counterbore of the spacing-collar. the counterbore of a spacing-collar.

2. In combination with a radiator having This specification signed'and witnessed'this 5 threaded lugs cast on the outside thereof, of 17th day of March, 1904.
